Idaho - A 2-year-old boy accidentally shot and killed his mother after he reached into her handbag at a northern Idaho Wal-Mart and her concealed gun fired, authorities said on Tuesday.
The 29-year-old woman was shopping with her son and three other children, Kootenai County sheriff's spokesperson Stu Miller told The Associated Press. Her family had come to the area to visit relatives, he said.
The woman, whose identity was not released, had a concealed weapons permit. Miller said the young boy was left in a shopping cart, reached into the victim's bag and grabbed a small-calibre handgun, which discharged one time.
Deputies who responded to the Wal-Mart found her dead, the sheriff's office said.
The woman's husband was not in the store when the shooting happened at about 10:20. Miller said the man arrived shortly after the shooting. All the children were taken to a relative's house.
The shooting occurred in the Wal-Mart in Hayden, Idaho, northeast of Spokane, Washington. The store closed and was not expected to reopen until Wednesday morning.
Brooke Buchanan, a spokesperson for Wal-Mart, said in a statement the shooting was a "very sad and tragic accident".
"We are working closely with the local sheriff's department while they investigate what happened," Buchanan said.
There do not appear to be reliable national statistics about the number of accidental fatalities involving children handling guns.
In neighbouring Washington state, a 3-year-old boy was seriously injured in November when he was accidentally shot in the face by a 4-year-old neighbour. The boy was wounded as the children played in a home in Lake Stevens, north of Seattle.
In April, a 2-year-old boy apparently shot and killed his 11-year-old sister while they and their siblings played with a gun inside a Philadelphia home. Authorities said the gun was believed to have been brought into the home by the mother's boyfriend.
Hayden is a politically conservative town of about 9 000 people just north of Coeur d'Alene, in Idaho's northern panhandle.
Idaho lawmakers passed legislation earlier this year allowing concealed weapons on the state's public college and university campuses.
Despite facing opposition from all eight of the state's university college presidents, lawmakers sided with gun rights advocates who said the law would better uphold the Constitution.
Under the law, gun holders are barred from bringing their weapons into dormitories or buildings that hold more than 1 000 people, such as stadiums or concert halls.
